Ethane at $45\mathrm{.}0C$ and $1\mathrm{.}30$atm $($abs$)$ flowing at a rate of $100\mathrm{.}0mo\frac{l}{s}$ is burned with $40\mathrm{.}0\%$ excess oxygen in air at

$175\mathrm{.}0C$ and $1\mathrm{.}30$atm $($abs$).$ The combustion products leave the furnace at $800\mathrm{.}0C$ and $1\mathrm{.}20$atm $($abs$).$

Oxygen Flow Rate

Include excess.

Account for stoichiometry.

What is the oxygen $(O_2)$ volumetric flow rate fed to the furnace?

$\frac{L}{s}$
